TIMER.

Application file d May 1 1,

'To all cto/0m z't may concer/1 Be it. known that I, HENRr 1V. Gossnnn, a citizen of the United States, and aresident of Verndale, in the county of Wadena and State of Minnesota, have invented a new and useful Improvement in Timers, of which the following'is a full, clear, and exact dcscription. 1

My invention relates to improvements in timers,l and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention to provide a timer in which the brush consists of a single piece of wire bent into a spiral, this brush making contact with wire spring contacts, whereby the metal construction of the ordinary timer is done away with.

A further object of my invention is to provide a device of the character described which has novel means for advancing or retarding the spark.

A. further object of my invention is to provide a device of the character described which is positively' operated and which makes a positive contact.

A further object of my invention is to provide a device of the character described which is placed away from the lower portion of the engine whereby it is freed from dirt, grease, and the like.

A further object of my invention is to provide a. device of the character described which is simple in construction, and is durable and eficient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features ofthe invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings,l forming part of this application, in which Figure 1 is a side elevation of the device as shown operatively applied to an engine.

Figure 2 is a. plan view of the device, and

Figure 3 is a perspective view of a portion of the device.

The present device is shown operatively applied to a Ford engine and it is obvious that with but slight modifications the device may be applied to anv internal combustion engine. The device comprises an angular'- shaped supporting frame 1 which is secured to the engine block 2 by means of bolts 3. The vertical portion of the frame 1 carries bearings #l in which a timer shaft 5 is 1922. Serial N0. 560,188.

journalled. The shaft 5 is positively rotated by the ordinary cam shaft 6 through a chain of gears l'. The shaft 5 has a wire contact making member 8 which is disposed between the bearings f1 and has its ends rigidly secured to the shaft. rfhe member 8 is fashioned into a` spiral which makes one complete revolution.

lnFigure 3 I have shown a` novel stationary spring` Contact member which comprises a wire 9 that is secured to a U-shaped bracket 10 at one end thereof. The. wire 9 is bent into a spring 11 which encloses the bracket 10 and is then bent upwardly at 12 and then laterally so as to make an arcuateshaped portion 13. The portion 13 is adapted to be contacted by the spiral 3 during' each revolution of the shaft 5. ln the present device I have provided four of these contact members 9, which are connected by means of the wires 23 with their respective primary coils in the coil box 22. y The brackets 10 are carried by a control insulating board 15, this board being operatively connected to the spark lever 16 in a manner now to be described.

The board 15 is held in adjusted position on the frame 1 by any means (not shown) and is adapted to move longitudinally with respect to the frame. As clearly shown in Figures 1 and 2, the sparlF lever 16 is operatively connected to the board 15 by means of a link 17, a bell crank lever 18.y and a link 19. It will be noted from this construction that a swinging of the spark lever 16 will move the board 15 longitudinally with respect to the frame 1. The frame 1 carries binding posts 2O which are insulated therefrom and which are electrically connected to the brackets 10 by means of a flexible wire 21. Each of the binding posts 20 is also connected to the coil box 22 by a wire s3. lVires 2st lead from the coil box 22 to the spark plugs 14. Then the device is actuated, current will flow from the ground through the spiral S and through any one of the wires 12 which happen to be in contact with the wire. Current will then flow on through the wires 23, the primaries in the coil box 22, and from the secondaries through the wires 24 to the spark plugs 14, and back to ground. This completes the circuit and causes the spark plugs 141 to ignite the gases within the cylinders at the proper moment. Two of the wires 23 are crossed so as to cause the spark plugs 14; to fire in the ordinary manner, i. e., l, 2, 4, 3.

From the foregoing' description of the various parts of the device, the operation thereof may be readily under bood. As heretofore stated, when the en: ne is started, current Will iioiv through' the Wire 8, and the stationary contacts 9 which will cause the spark plugs rl to ignite the Within the cylinders yt the proper moment. The shaft with the Wir 8 forms a ver)7 simple means b v which the circuit is closed through the various members 9 at predetermined intervals. lf desired. the frame l may be enclosed by a easing; (not shown) so as to keep the moving parts free from dust, dirt, and the like.Y r)The wires lil are yieldingly carried by the brackets l0 and therefore forni a Close Contact with the Wire 3 as it engages therewith. A positive contact between the Wire 8 and ine portion l?) is therefore assured.

In case the operator Wishes to advance or retard the spark, he aetuates the spark lever 16 in the ordinary manner. is heretofore stated, this lever is operatively connected to the board l5 whereby movement thereof Will move the board l5 longitudinally With respect to the frame 'L A. sli, .ht movement of the board l5 with respect to the :frame l will move the contact members 9 With respect to the Wire 8, whereby the closing of the circuits through the members 9 Will be changed. In this manner, the spark is advanced or retarded at the will of the driver. rhe device does not interfere with the ordinary operation of the engine and can be readily installed with but slight expense. rlhe board l5 is provided with slots 25 into Which the binding posts 2O project. These slots permit the board l5 to be moved with respect to the frame l when it is desired to advance or retard the spark. lt is obvious that this circuit will always be closed Whether the board 15 is move-d or not. The device is disposei'l above the lower portions of the engine and is therefore not likely to accumulate grease or the like which the timer of Ordinar)v construction has 'to contend with.

l claim:

A timer for internal combustion engines comprising a frame, a timer shaft rotatablY carried by said frame, means connected with the crank shaft of the engine for rotating` HENRY W. GOSSELL.
